I have posted on here before but now I have a new idea and with this new idea comes new obstacles..So I am going to build myself a box for my MTX 7515. I went to the MTX website and it says the best enclosure is 2.42 ft^3 tuned at ~34hz.

The port is 2" wide, which is little bitty. What would increasing the width and increasing/decreasing the height of the port do to the movement of air and/or sound??

Anyone think that building the box 3-3.5 ft^3 would be better?

Also, I am wanting to build the box SUB UP and port BACK. Which port design is better?
(Rough sketch lol)
